Information Law analysis: In its judgement of 4 October 2024, the European Court of Justice ruled, that the provisions of Chapter VIII of the EU’s General Data Protection Regulation, Regulation (EU) 2016/679 (EU GDPR) do not preclude national rules which grant undertakings the right to rely, on the basis of the prohibition of acts of unfair competition, on infringements of the substantive provisions of the EU GDPR allegedly committed by their competitors. The court further ruled that the data of a pharmacist’s customers, which are provided when ordering pharmacy-only but non-prescription medicines on an online sales platform, constitute ‘health data’ within the meaning of Articles 4(15) and 9 of the EU GDPR (to that extent contrary to the Advocate General’s opinion of 25 April 2024).
